Design and Development of a Thrust Vector Control Model Rocket for High-Altitude Payload Delivery

Abstract

This study presents the design and development of a Thrust Vector Controlled (TVC) model rocket to enhance high-altitude payload delivery for applications such as disaster relief, scientific research, and remote region support. Unlike UAVs, which face payload and altitude limitations, the proposed TVC rocket ensures stable ascent, precise maneuverability, and adaptability in low-density atmospheric conditions. The system integrates advanced control algorithms with sensor fusion, a dual-axis actuator mechanism, and a modular flight computer employing Kalman filtering and PID control. Stability analyses were supported by simulations using OpenRocket and validated through water-pressure chamber experiments, grid fin integration, and a dual-axis reaction wheel system. Results confirm significant improvements in responsiveness, orientation control, and resilience to disturbances. The rockets performance demonstrates practical feasibility for cost-effective, reusable, and scalable missions, offering a reliable platform for time-sensitive payload delivery in inaccessible areas. This work establishes a foundation for future advancements in highaltitude transport systems, bridging critical gaps where UAVs remain ineffective.
